Check Valve
KEYSWON check valves conform to API 6D, API 594, BS 5352, BS 1868, and ASME B16.34 standards. Our check valves can come in sizes of 1/2" ~48" and nominal pressure of 150~2500lbs.
Our company is a major industrial valve supplier in China and offers check valves with highly durable cobalt-based hard alloy sealing surfaces. The weld overlay cladding provides wear resistance, corrosion resistance, and scratch resistance which leads to an extended lifespan for our non-return valves. Its self-tightening sealing structure enhances the valve cavity’s sealing performance as the pressure increases.
Features
1. The valve disks have a short stroke and the check valve is sensitive for quick and easy shutoff.
2. Our clack valve is a multi-purpose valve applicable for both horizontal and vertical pipelines due to its lower surge pressure.
3. The ports of our check valves are smooth and feature small fluid resistance.
